iio: Fix two mpl3115 issues in measurement conversion

2014-06-26T19:17:36Z

commit d29f592929489d0a7c414396fae28119f3d280e1 upstream. (i) pressure is 20-bit unsigned, not signed; the buffer description is incorrect; for raw reads, this is just cosmetic (ii) temperature is 12-bit signed, not 16-bit; this affects readout of temperatures below zero as the sign bit is incorrectly processed reported via private mail Signed-off-by: Peter Meerwald Reported-by: Robert Deliën Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio: Fix endianness issue in ak8975_read_axis()

2014-06-26T19:17:36Z

commit 8ba42fb7b17649c9ab5b5e79d4e90370a0b4645e upstream. i2c_smbus_read_word_data() does host endian conversion already, no need for le16_to_cpu() Signed-off-by: Peter Meerwald Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio: adc: at91: signedness bug in at91_adc_get_trigger_value_by_name()

2014-06-26T19:17:36Z

commit 4f3bcd878f1d3c730fe00f619b7260c6125d49eb upstream. at91_adc_get_trigger_value_by_name() was returning -ENOMEM truncated to a positive u8 and that doesn't work. I've changed it to int and refactored it to preserve the error code.

iio: adc: checking for NULL instead of IS_ERR() in probe

2014-06-26T19:17:36Z

commit e94f62e79f7f63a68574ee5e76c19837ec12f3db upstream. mcb_request_mem() returns an ERR_PTR(), it doesn't return NULL. Fixes: 74aeac4da66f ('iio: adc: Add MEN 16z188 ADC driver') Signed-off-by: Dan Carpenter Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio:adc:max1363 incorrect resolutions for max11604, max11605, max11610 and max11611.

2014-06-26T19:17:36Z

iio: adc: Nothing in ADC should be a bool CONFIG

2014-04-26T10:22:16Z

The whole IIO subsystem can be built as modules. If you make it a module then stuff marked as "Y" in the adc directory simply won't be linked in properly. The two configs that were wrong were EXYNOS_ADC and LP8788_ADC. I know for a fact that EXYNOS_ADC will work as a module. I assume LP8788_ADC will also be fine.

iio: exynos_adc: use indio_dev->dev structure to handle child nodes

2014-04-26T10:19:40Z

Using pdev->dev with device_for_each_child() would iterate over all of the children of the platform device and delete them. Thus, causing crashes during module unload. We should be using the indio_dev->dev structure for registering/unregistering child nodes.

iio:imu:mpu6050: Fixed segfault in Invensens MPU driver due to null dereference

2014-04-26T10:14:51Z

The driver segfaults when the kernel boots with device tree as the platform data is then not present and the pointer is deferenced without checking it is not null. This patch introduces such a check avoiding the crash. Signed-off-by: Atilla Filiz Signed-off-by: Jonathan Cameron Cc: Stable@vger.kernel.org

Jonathan writes: First found of IIO fixes for the 3.15 cycle. * Fix the platform data support for the at91 adc driver. * A couple of related follow up patches get the support working again for at91sam9260 and at91sam9g45 as the earlier patch results in a device name change. * A default timer value in the at91 adc driver was bonkers. Make it sane. * Fix incorrect reporting of the integration time for the cm32181 light sensor * Fix a missing break in the ad2s1200 driver which would have give a false error return. * Make sure buffer scan mask queries from userspace return 0/1 rather than a fairly random value depending on their implementation of test_bit * Fix leak of the i2c client and a null pointer dereference in the cm36651 driver. * Fix a build warning on avr32 for the mxs-lradc (not exactly a critical combination - but the issue was real).
